hey I just bought my 94 camaro with an ls1 swap and the speedometer is way off. what do I need to do to calibrate it, or where can I take it to get it done in the miami area?

all the wiring, dash, and console have been changed to a 98.

 

does the car have gears? if so the pcm needs to be played with....get your car tuned with us and the tuner fixes it
